Abstract
Embodiments of a variable inductor and a communication device are generally described herein. The variable inductor may comprise a signal wire and a control wire to receive a direct current (DC) control current. The variable inductor may further comprise a magnetic material integrated with the signal wire and the control wire. When a DC control current applied to the control wires takes a first current value, an inductance between an input node and an output node on the signal wire may take a first inductance value. When the DC control current takes a second current value, the inductance between the input node and the output node may take a second inductance value.
